Definitions

  • This invention relates to a method of detecting cows which are on-heat, and apparatus therefor
  • Milking cows are generally kept pregnant every year to maintain lactation In winter, the cows are kept in sheds A cow's ovulation cycle is about three weeks, and it is obviously important for insemination to catch the cow at the right point of her cycle
  • Two prior suggested methods of detection involve either pressure sensors on the cow's rear, or a pressure sensor on the cow's feet or on the floor to measure activity or weight differences
  • ordinary scratching by a cow of its rear can activate the first type of sensor, and in a cow shed with tens or hundreds of cows, there is always significant movement of the cows causing constant activity and weight differences
  • a method of detecting a first cow when mounted by a second cow wherein one or more beams of light are directed wholly or substantially horizontally at one or more detectors, and at a level above the first cow and corresponding to the additional height of the second cow when mounting the first cow, such that the mounting of the first cow by the second cow breaks one or more of the beams of light to one or more of the detectors, and the or each detected break causes activation of an alarm means or a cow identification means or both
  • the present invention provides an automatic method of alerting when a cow on heat, and/or of immediately identifying a cow on heat, which is only activated as and when the cow allows herself to be mounted
  • the alarm means and the cow identification means could be used together either simultaneously or independently
  • Suitable forms of light beams include a laser and a light emitting diode Where a single beam of light is used, the beam may be stationary but pass over a relevant area above the cows Preferably the light beam scans an area, more preferably by rotation The beam may be rotating constantly in one direction, or reversibly rotating across a sector
  • the beams may again be stationery, and arranged in parallel or in two or more different directions across a relevant area Alternatively, each light beam is rotating
  • a plurality of light beams whose paths overlap, either simultaneously or intermittently, further provides directional information on the location of the relevant cows Any breaks in two or more of the beams caused by one mounting event may not occur simultaneously, especially if the beams are rotating However, the multiple beam breakage should still occur contemporaneously for the same mounting event, so that locational information on the relevant cows is still achievable
  • the or each beam of light may also be transmitted constantly or intermittently, e g pulsed
  • the frequencies of two or more beams of light may also be different to assist detection of which beam or beams are being broken by one detector or neighbouring detectors, possibly using matched frequency detectors
  • the or each detector may be located remote from the source(s) of light Any means for detecting the receipt of a beam of light is suitable, e g a photodiode
  • the or each detector could be dedicated, unidirectional and/or be designed to receive only one light frequency, or be of a more general nature
  • the or each beam of light is reflected by one or more reflective means to one or more detectors
  • Such detector(s) could again be remote from the or each source of light, or could be near or adjacent to the light source(s), possible within the same housing
  • the reflective means could be discrete or continuous, and could comprise one or more mirrors, or be a retroreflective strip or series of discs able to reflect light directly back independent of the angle of incidence
  • the alarm means could be an audio, visual or electronic signal adapted to alert a farmer of mounting activity, to which he can then respond by visiting the cow shed
  • the invention uses a cow identification means
  • the means for identifying the cow on-heat could be an active or passive means, i e a means able to mark the first cow or provide a mark able to identify the first cow for subsequent detection by the farmer, or a means of remotely identifying the cow, e g on one or more cameras
  • the first cow could be identified from its freeze-brand or other normally applied marking, or be marked with an additional preferably photogenic identifying mark such as video coding
  • the identification means may also be able to identify the second mounting cow, if desired or necessary
  • the identification means could be located remotely from the or each light beam or the or each detector, or alternatively near or adjacent thereto Using one or more directable cameras as the identification means, such cameras generally having different locations, should increase the chances of positive identification of the relevant first cow Different identification means could be connected to different light beams Alternatively, the locational information from all the detected broken light beams could be centrally processed to singularly focus the, some or all of the identification means towards the calculated mounting location
  • two or more beams of light and two or more detectors are used, and the detectors work in partnership to co-ordinate two or more differently located cameras to the location of breakage of the light beams
  • an apparatus for detecting a first cow when mounted by a second cow comprising one or more beams of light, one or more light detectors, and an alarm means or a cow identification means, wherein the or each beam of light is directed wholly or substantially horizontally at one or more detectors at a level above the first cow and corresponding to the additional height of the second cow when mounting the first cow, such that the mounting of the first cow by the second cow breaks one or more of the beams of light, and the or each detected break causes activation of the alarm means or cow identification means or both
  • the present invention could be used in relation to one cow to be detected, or simultaneously for a small or large number of cows
  • the relevant cows could be particularly targeted, and possibly have their freedom of movement limited, or they could be allowed to roam over the area covered by the light beam(s) and detector(s)
  • a number of light beams and detectors are preferred to cover the relevant area
  • a passive sensor is directed wholly or substantially horizontally a level above the first cow and corresponding to the additional height of the second cow when mounting the first cow, such that the mounting of the first cow by the second cow activates the sensor by altering the field of detection, and the sensor causes activation of an alarm means or a cow identification means or both
  • the passive sensor could be a passive infra-red sensor, similar to those commonly used in room and outside security systems which activate on movement within the field of detection
  • the present invention is applicable to all cows whether they be dairy cows beef cows or otherwise It is equally applicable to other farm animals, such as pigs, which are bred or inseminated in a similar manner

  • Fig 4 is an enlarged side view of the apparatus in Fig 3
  • Fig 5 is an image recorded by the camera in Fig 4, and Figs 6 and 7 are two alternative arrangements for the present invention
  • Fig 1 shows a first cow 2 being mounted by a second cow 4, similar to mounting by a bull
  • the first cow 2 allows herself to be so mounted when she is on-heat
  • the mounting is a clear and obvious signal that the first cow 2 is ready for service, either naturally or using artificial insemination
  • Fig 1 also shows two height dimensions
  • a suitable additional height of the mounting second cow 4 above the first cow is "B”
  • Fig 2 shows a typical arrangement of two parallel lines of cattle stalls in a cow shed 5
  • the stalls 6 are where the cows rest and sleep, and they are not usually wide enough or otherwise convenient for one cow to mount another cow therewithin
  • the run 8 is the general mixing and walking area for the cows and it is generally in the run 8 that mounting occurs
  • Fig 2 also shows three units 10 housing apparatus according to the present invention, spread along one back wall 12 of the shed 5 Also shown is the coverage of the run 8 by the units 10
  • the units 10 cover most of the run 8, and are intended to be side-on to the general direction of the cows along the run 8 to achieve the greatest view of the cows for better and easier identification
  • On the opposite wall 14 and adjoining sides of the cow shed 5 are a series of wall mounted retroreflective discs 16 able to return a beam of light at whatever angle received from a unit 10
  • Fig 3 shows the first and second cows 2,4 of Fig 1 head on in the run 8 of the cow shed 5 in Fig 2 Also shown is a unit 10 and cattle stalls 6
  • Fig 4 shows the contents of the unit 10 in detail
  • the unit 10 houses a laser 20 and an almost co-axial photo-detector 22 at an upper end, and a video camera 24 at a lower end as a cow identification means In between are upper and lower aligned co-axial mirrors 26,27 respectively, which are rotatable on the shaft of an attached motor 28
  • the laser 20 creates a beam of light 30 which is reflected by the upper mirror 26 to travel through a cutaway 32 in the unit 10 and across the cow shed 5 wholly or substantially horizontally at a level corresponding to the additional height of the second cow 4 when mounting the first cow 2 (B in Fig 1 )
  • the light beam 30 is reflected back to the unit 10 by the retroreflective discs 16, and the reflected beam is reflected back by the rotating upper mirror 26 to the detector 22
  • the beam 30 will naturally broaden over distance, such that the detector 22 is able to see the edge or penumbra of the beam 30
  • the motor 28 rotates both mirrors 26, 27 either continuously or in an arc corresponding to the desired area of cover Continuous rotation could cover 360°.
  • An arc of rotation could be 180° if one unit 10 was used to cover an area from a side wall. In the present cow shed 5, the angle of rotation is about 90°, as shown in Fig. 2.
  • the mirrors 26,27 are continuously rotated, but non-reflection of the beam 30 (and hence non-detection by the detector 22) when rotating within the housing is accounted for.
  • the rotating upper mirror 26 sends out and reflects the laser beam of light 30, which, if it is not broken by any mounting cows, is reflected back to the detector 22 by the retroreflective discs 16.
  • the detector 22 takes account of the breaks in received light because the retroreflective discs 16 are discrete. Where the second cow 4 mounts the first cow 2 as shown in Fig. 3, the light beam 30 is broken, and no return beam is received by the detector 22.
  • the detector 22 then activates the video camera 24 to view and preferably record the event. The activation may be continuous from the detected break, or time delayed or sequenced to fit with rotation of the light beam 30 where broken.
  • the camera 24 could possibly be activated after the beam 30 is detected as broken two or three times at the same point of rotation, to provide confirmation of mounting and avoid any brief and/or accidental beam breaks for other reasons.
  • the video camera 24 maintains alignment with the direction of the light beam 30 via the co-axial lower mirror 27.
  • the lower mirror 27 is angled so as to view the particular area of interest, i.e. the level of the first cow 2 in the run 8. Some or all of the second cow 4 may also be seen by the camera 24, and a typical image is shown in Fig. 5.
  • the cows 2, 4 may have identification marks 32 on their sides to help increase their identification to the farmer.
  • the image may include recordal of the time to help confirm the timing of the cow's ovulation.
  • a cow is on heat for an average of eight hours, but it can be as short as only two hours. Such a period could well be in the middle of the night when the farmer is unlikely to be present to see any mountings.
  • the camera 24 is deactivated.
  • the video camera 24 signal could be played live on a screen remote from the cow shed 5, e.g. in the farm kitchen.
  • the video camera images could be stored for viewing at a later time convenient to the farmer.
  • the images could also be processed by suitable electronics to provide a more viewable recording.

  • the apparatus required is simple and easy to install in areas housing cows.
  • the apparatus can be located above the normal height of the cows so that they cannot damage it.
  • the method is also non-intrusive. Variations and modifications can be made without departing from the scope of the invention described above.

Abstract

L'invention concerne un procédé servant à détecter le moment de la monte d'une première vache par une deuxième vache. Un ou plusieurs faisceaux de lumière sont dirigés totalement ou pratiquement horizontalement vers un ou plusieurs détecteurs, ainsi que vers un niveau situé au-dessus de la première vache et correspondant à la hauteur supplémentaire de la deuxième vache quand elle monte la première vache, de sorte que la monte de la première vache par la deuxième vache vient couper un ou plusieurs de ces faisceaux de lumière dirigés vers un ou plusieurs de ces détecteurs et que la détection de la coupure ou de chaque coupure provoque l'excitation d'une alarme ou de moyens d'identification de la vache ou des deux. La monte indique au fermier que la vache est prête à être inséminée et l'invention met en place un procédé automatique d'avertissement des chaleurs d'une vache ou d'identification immédiate de la vache en chaleur, qui est excité uniquement lorsque la vache se laisse monter et simultanément à la monte. On utilise, de préférence, deux ou plusieurs faisceaux de lumière et deux ou plusieurs détecteurs et ces derniers travaillent en collaboration afin de coordonner deux ou plusieurs caméras placées à des endroits différents en direction du point de coupure des faisceaux de lumière.
